Spinel compounds LiNi 0.5 Mn 1.3 Ti 0.2 O 4(LNMTO) and Li 4 Ti 5 O 12(LTO) were synthesized by different methods.The particle sizes of LNMTO and LTO are 0.5-2 and 0.5-0.8 μm,respectively.The LNMTO/LTO cell exhibits better electrochemical properties at both a low current rate of 0.2C and a high current rate of 1C.When the specific capacity was determined based on the mass of the LNMTO cathode,the LNMTO/LTO cell delivered 137 mA·h·g-1 at 0.2C and 118.2 mA·h·g-1 at-1C,and the corresponding capacity retentions after 30 cycles are 88.5% and 92.4%,respectively.
